10 Claims. (OI. 495) The present invention relates to means for automatically molding glass or like articles or objects from molten or plastic material.

Among the objects of the invention is to .provide a novel -means for moving in given time relation a plurality of series of molds, such as matrix molds, to and from a common mold charge feeding station, together with means for coordinately moving the series of molds to and from molding stations, whereby when a mold of a series is being fed with a fresh mold charge a mold of another series is at' the molding station for the molding of'the mold charge previously fed to it at the feeding station. 3

Another object of the invention is to provide novel means in association with each mold (of each seriesfor transferring or delivering the molded end product to a conveying means in given time relation coordinated with the molding of a successive mold charge in another mold of .the

such as two by way of illustration, of turntables rotatably supported on the reciprocating.car-

riage, each of the turntables carrying a series of old elements or parts, such as matrix mold par s, and means for turning the tables with predetermined angular movements in giver time relation with the reciprocatory movements of the The latter means maycomprise a slipdrive means which may be in the form of a rack and gear means, with overrunning clutches so related to the carriage and the turntables that in one stroke of reciprocatory movement of the carriage one of the turntables will be turned as it is being carried by the carriage, while another turntable is merely moved linearly with the carriage without turning, and vice versa, during the reverse stroke of the reciprocatory movements of the carriage. In'"*this way the matrixmold of the series on the former table, which matrix mold has received a fresh mold charge at the'feeding station, will be moved both by the turning movement of the turntable andits linear movement with the carriage to a molding station, that is, in al nement with a patrix type 'of mold party. while simultaneously a matrix mold of the series on the other or latter turncharge is fed to the latter matrix mold at the feeding station; r

Also each matrix mold on each table has means for transferring or delivering the mold charge or article to suitable conveyor means. The transfer means preferably operates during the dwell or rest period at the end of each stroke of the reciprocatory movements of the carriage and turntables, and simultaneously with the molding at one or the other of the molding stations, which may be also at the same time as when feeding a fresh mold charge at the feeding station. Such transfer means may include rack and gear means associated with each'matrix mold to swing the latter when the rack and gear means is operated. Also associated with each table at its outer dwell or' rest position is -a lifter means so located as to -be directly under the rack and.

gear means of the matrix mold brought in position opposite the lifter means by a combined turning of the turntable and the movement of the carriage, at which time suitable time control means, such as pneumatic means, operates the lifting means which in turn actuates the rack and gear means to cause the matrix mold to swing and to drop the molded article carried by it onto the conveyor means. j

While the patrix mold means is adjustably mounted on the machine so that they maybe brought into substantial alinement with the matrix molds successively moved opposite them, in

practice, due to certain tolerances of manufacture, it is diflicult always to have .all of the matrix molds of a series come exactly'in axial coincidence with the corresponding patrix mold. Hence the present invention comprehends the providing of counterpart, tapered or beveled surface portions on the matrix and patrix molds so that as theyapproach each other in the molding function these tapered surface portions will con-- tact at some point and mutually self-center themselves into exact coaxial relation before the table, which matrix mold is empty, is moved 7 linearly with its non-turning turntable and the carriage to the feeding station, that is, in alinemolded in the mold cavity between the molding surfaces of the matrix and patrix mold parts.

A further object of the invention is toprovide novel means for simultaneously moving a to a molding station, and a further mold part to mnt with the means for feeding a fresh m ld 5 a transferring or delivering station, and in simultaneously feeding a mold charge at a feeding station, molding a mold charge at the molding station, and transferring or delivering a molded article at a transferring or delivering station.

The invention comprehends an automatic molding of glass articles by reciprocating a carriage with a given stroke and with dwell periods at the ends thereof, together with the carrying of spaced turntables rotatably carried by the carriage and with a' circular series of matrix molds on each turntable, 'which molds travel in given paths below a given feeding locus above the turntables, the latter being spaced relative to the length of the stroke of the carriage to have the paths of movement of the series of the matrix'mold respectively directly below the locus of the feeding means when the carriage is retogether with spaced patrix type of .molding means located respectively over the matrix mold paths of the respective turntables when the carriage is respectively at its ends of its reciproca-.

tory stroke. In'other words, the series of matrix molds-are so moved and related to the stroke of the carriage as to successively pass. through a given common point, namely, the locus of feeding, first a matrix mold of one series and then a matrix mold ofthe other series. Likewise the matrix mold of each series passes through the respective molding station of that series. Thus it will be seen that the invention having the twin units mentioned. besides being capable of pro ducing pressed ware of any kind, has double production capacity and speed, while using but a single delivery station. Another advantage possessed by the present invention is that the molds to be charged are brought into direct vertical alinement withthe feeder or delivery orifice so that the gob or. mold charge will fall in a straight line and axially into the molds.

Other objects, advantages, capabilities, features, process steps; and the like, are comprehended by the invention as will later appear 'and as are inherently possessed by the invention.

Referring to the drawings:

spectively at its ends of its reciprocatory stroke,

I. In the, track 2 slidably reciprocates a carriage 3 having a pair of standards 4 and 4 each comprising spaced upright sides 4 and 4 (see Fig. 5), in which respectively is rotatably supported a shaft 5, l5". Each of the latter has a protruding end portion 3, 3 to which is secured a ratchet wheel I, 1". Fixedupon thetrack 2 and located at the sides of the base portions of the .carriage 3 are guide members 8 and 9. The top of the member 9 has rack teeth constituting a rack III with which operates spur gears II and II freely rotatable on the protruding shaft portions 6 and 3' respectively. These gears carry pivoted pawls I2 and I2. which are respectively operative with the ratchets I and 'l, the pawl l2 looking with the ratchet I in counterclockwise rotation of the gear II, and the pawl l2 looking with the ratchet 1' in clockwise rotation of the gear II, as viewed in Fig. 4. Secured to each of the shafts 5 and 5 is a beveled gear l3 operative with a beveled gear [4 (see Figs. 5 audio) Each of the gears H has a hub l 5 fixed to a vertical shaft l8, l3 (seeFigs. 2, 3 and 10) rotatable in head [1, l1 suitably secured to the reciprocating the carriage, the other end of the link being pivotally connected by way of pivot means 22 to a lever 23 in turn fulcrumed by way Fig. 1 is a view in front elevation of the de- Fig. 51s a part transverse sectional view and part end elevational view,'taken in a plane as represented by line 5-5 in'both Figs. 1 and 4 of the drawings.

Fig. 12 is a fragmentary view in elevation of the cam means, on a reduced scale, effecting a dwell at the end of the stroke? Referring more in detail to the drawings, the embodiment selected to illustrate the invention is shown in a machine having a base I support-' ing a guide track 2 suitably secured to the base of pivot means 24 at an end of a compensating link means 25 pivoted by way of pivot means 23 in bearing means 21 fixed to an end of the base I, the other end of the lever 23 being pivoted by way of pivot means 28 to. a reciprocating rod 23 suitably operatively connected to a cam K having a cam groove L of which portionM is a dwell part of the cam. In the cam groove extends a follower N in the form of a pin secured to the reciprocating rod 29 slidable in guides P. As the cam rotates the bar is reciprocated according to the form of the cam groove, and while the dwell 1 portion M of the groove is traveling past the pin N the slide bar 29 is at rest or dwell.

Each of the turntables carries a plurality of molding die means. In the illustrative embodiment shown there are six of these to each tumtable. They are all alike and one is shown by way of example in detail in Figs. 6, 7, 8 and 9 of the drawings. It will be understood that the inupon the size of such mold means. These mold means are arranged in a series to travel in circular paths as the turntable is turned or angularly moved. I

Each of such means comprises a base plate 33 secured'to the top of the turntable as by screws or other suitable mode of securement. The plate 30 has hinge lugs 3 l carrying a hinge pin 32 rotatable in such lugs. Secured to/the pin 32 between the lugs 3| is a lug'33 integral with a mold carrier 34 which, in the form of device chosen to illustrate the invention, is of annular form and has a plurality of diiferent'sized sockets for selectively accommodating different sized -mold parts, but it is to be understood that suchcarrler may be of any desired shape to conform with the particular shape of mold part used. The base 35 of the carrier 34 is provided with a beveled seat 36 to seat properly on a counterpart part 3% on the carrier. 3

in the carrier 35.

plate 30, as shown in 34 is swung to seat- 30 it should not be 36 and 3? when will causea Proper will seat firmly and in correct coaxial position.

A mold die part 38 of matrix type is shown by way of example. It is designed to mold colored glass lenses or the like as may be used in tail light devices on vehicles, or as reflectors, etc., and they are usually of red color but not limited thereto. The mold part 38 has a tapered seat 39 to fit with the tapered seat 46 on the carrier 3%, which seats serve to properly center the mold In the form shown. the mold part 38 is seated in If a smaller mold part be used, it may be seated in a correspondingly sized lower socket provided The mold part 33 has a threaded stem 52 extending through an aperture in the base 35 of the carrier and to which a nut 43 is applied for securely holding the mold part 38 in place on the carrier 36. The turntable l8 also is provided with a suitable recess or hole M for affording clearance for the stem ii and the nut is.

The hinge pin or shaft32 has an extension 35 (see Figs. 6 and 'l') to which is fixed a spur gear 46, and between this gear and the lug ii is a coil spring i'i so connected to the shaft extension 35 and the base plate lug 3! as to turn the shaft 32 and the connected carrier 36 with the mold part 33 all as a unit to seated position, as shown in full lines in Fig. 9, and to normally hold the same in such seated position.

To the under side of each turntable (see Fig. 7) are secured in any suitable manner a series of brackets or saddles 48, each of which slidably receives the shank d9 of a vertical rack 58 which is vertically sl-idable tangular hole i provided in the turntable, and

so located that the rack 56 will be in mesh with.

the spur gear 66. When the rack 58 -(see Figs. '7 and 8) is movedupward it turns the gear 46 counterclockwise, as viewed in Fig. 8, and swings the mold carrier 30 with the mold part 38 as a unit against the counter-force of the spring Hi from the full line position shown thereof to the dotted line position shown thereof in Fig. 9, whereby the molded article 52 is dropped upon a conveyor 53 or 53, later described, When the rack 50 is released, the spring M then acts to turn back the gear 46 and the mold carrier 3d with the mold part 38 to the seated position shown in full lines in Fig. 9, while at the same time the gear 56 pushes the rack 58 down to the position shown in Fig. 8. The lower end of the rack is shouldered to seat on the base partof the bracket or saddle 48 (see Fig. 3)

The means for lifting lifterdevice 5 3. there being one of these at each end of the track 2 in operative relation with the turntables when at their respective ends of the reciprocating stroke of the carriage (see Fig. 1). Each of such means comprises a jointed lifter rod having segments 55 and 58, of which the latter has a head 51 for engaging the lower end of the rack shank 49 when it arrives just over the head 51 (see Fig. '7). The rod part 55 is vertically slidable in a sleeve 58 fixed in position on the upper socket ti.

through a square or rec-- the rack 50 comprises a 51, such next shank d9 (see Fig.

the top of the track plate 2. The latter and the 7 base i are suitably apertured for the passage of the segment 55 to extend downward into contact with an arm of .a lever '59 (see Fig. 5) pivoted by ends of a spring apart by connecting means 36-38 is swung to deliver or dump the molded article.52 on the conveyor 53 or 53. Upon the release of air pressure in the cylinder 62, 'the partsmentioned above return and the mold means is seated on the base plate 3@ (see Fig. 9)

Each lifter means 58 has a joint of the "foot rule type, whereby the joint will open or break in only one direction. If for some reason the full descent of the lifter means-54should not occur when the rack shank Q9 leaves the head 51 as the turntable is turned to bring the next rack shank 69 in position to be over the head 11) may contact the head 51 and the segment 56 will swing, as shown in Fig. 11, so that the can clear and not break or otherwise damage the lifter means. If any such condition should exist in the machine, any suitable type of auto-.

to correctthe condition. The segments 55and 5t carry anchor pins 63 and M to which the are connected, the spring having aloop 65 convoluted about the pivot pin 8? of the joint. Normally the spring 55 maintains the segments 55 and 56 in alinement, as shown in Fig. 7, but yields to ing of the joint, as shown in Fig. 11.

There is a molded article conveyor for each turntable, as designated '53 and 53 in Figs. 1, 2, 3 and 4; these conveyors'being downwardly inclined to the left, as showr'r'in' Fig. 1, and spacedly held side pieces 68 and 5% so that the conveyors may be r'eciprocated or oscillated in unison and still be operative with relation to their respective turntables it and it These conveyors are supported on pivoted link struts 1d and H (see Fig. 1), pivoted at their lower ends by way of pivot means-l2 and i3 secured to the top of the guide plate or track 2, and at the upper ends by way of pivot means i l and 15 fixed respectively to the under sides of the conveyors 53 and 53. To the strut iii is pivotally connected a reciprocating or oscillating link 18 by way of pivot means ill fixed to the strut 10, the other end of the link it being operatively connected to a crank it on a shaft It rotative in suitable bearing means til and 8| supported on the guide plate 2. The shaft 19 carries a pulley 82 suitably driven by a belt (not shown) from the motive operating part of the machine. The rotating of the crank 18 causes, by way of the link 15, an. oscillation or jiggling of the conveyors so as to cause the delivered articles thereon to slide down the conveyors as by impulses, or as by a series of short next shank (i9 permit the breakturntable is. a patrix type of molding die means. They comprise the die parts 83 and 83 which descend and press the plastic material in the matrix mold part 38 then under the patrix die part 83 or 83 as the case may be. Each patrix molding part 83 or 83 is carried at the lower end of a plunger 84 secured at its upper end to a cross head 85 carried on a plunger or piston rod 86 operatively connected with a pneumatic device having a cylinder 81 suitably adjustably supported by way of a bracket 89 on a post 98 fixed to the base I. On the post 98 is also adjustably secured a. guiding bracket 88 through which'is slidably guided the plunger or piston rod 88. To the plunger 84 is fixed a plate 9I carrying a plurality of rods 92 encompassed by springs 93. Slidable on the plunger 84 and also on the rods 92 is a movable plate 94 which acts as a backing plate .for the patrix mold. When the patrix mold descends, this plate 94 will first contact with and come to a stop upon the top of the matrix mold part 38, while the mold part 83 or 83 will continue to descend further to mold the plastic article in the matrix mold part 38. The plunger 84 and the spring rods 92 will then slide through the plate 94 which is held at rest.

The patrix mold part 83 or 83 is shown more in detail in Fig. 9. It has the molding part 83 with the particular contour to give the counterpart configuration on a side of the article being molded. It may have recesses 83" to form protuberances on the article. Above the mold part Bil-83 the plunger end has a tapered portion 83 to cooperate with the tapered portion 38 provided at the top of the matrix molding die part 38, as shown in Fig. 9. If when the patrix die 83 or 83- on descending should be slightly off center or not coaxial with the matrix die part 38, as illustrated by the center lines 95 and 98 (see Fig. 9), the beveled or tapered portion 83 will contact the beveled or tapered portion 38 of the mold die part 38 and the patrix mold die part 83 or 83 will be laterally shifted to exact coaxial relationship. Besides the tapered portions 83 and 38 will also limit the downward movement of the patrix mold die part, thus acting as a gauge and preventing excess displacement. of the plastic material of the article being molded.

The molten material from which the articles are made issues at a given or predetermined rate from the usual outlet at the base 91 of the melting means in the form of a gob or mold charge 98, substantially of the shape or form shown in Figs. 1 and 4. It is cut or severed by the shear blades 99 in the usual way. The "gob then moves down an inclined chute or trough I08 extending to a funnel I8I, where it drops and thence drops from the funnel upon the matrix mold 38 then located directly beneath the funnel. Both the chute I 88 and the funnel given time relation so as to be delivered by way of the chute I88 and funnel I8I to the matrix molds .at predetermined points of time related to the or period of rest at each end of the reciprocation IM may be carried on suitable arms I82 and I03 adjustably supported on suitable supports (not shown) on the machine. In this way the chute and funnel may be adjusted in accommodation to the locus of the gob delivering outlet means and the locus of the matrix mold part then in position for receiving the mold charge or gob. In this way the funnel I8I may be adjusted to be exactly centered over the matrix mold part receiving the gob and the chute I88 adjusted to properly transfer the cut or sheared mold charge to the funnel IOI.

In operation the gobs 98 of glass or like plastic material are successively formed and sheared in of the carriage and parts carried thereby. Also at the same time the conveyors 53 and 53 are being oscillated or jiggled by way of links I8 and crank I8, etc.

Assuming the parts to be in the position shown in Figs. 1, 2 and 4, and viewing particularly Figs. 1 and 2, the carriage 3 and the turntables I8 and I8 are at the left hand end of the stroke and at dwell or rest. On the table I8 is an empty matrix mold part 38 at the position A (see Figs. 1 and 2) directly under the funnel III,

which is the position at which the matrix mold part is receiving a gob or mold charge from the funnel. At the same time, another matrix mold part 38 on the turntable I8 and which contains a, previously received gob or mold charge is in position B (see Figs. 2 and 4) directly below the patrix mold part 83. The pneumatic means (of any suitable form) is now acting to move the patrix mold part 83 down to mold the mold charge in that matrix mold part, after which the patrix mold means rises. -While this is occurring, a previously molded mold charge which has been carried by the turntable I8 in the previous stepping around thereof in the direction of the arrows shown on the turntable has reached the position C and has been dumped at the position C onto the conveyor 53 (see Fig. 2),

The next action is a'reciprocation of the carriage 3 with the parts carried by it to the right to the position shown in Fig. 3. The matrix mold part at the dumping position C (Fig. 2) returns to its original position on the turntable because the lower end of the rack shank 49 has left the head 51 of the lifter means 54. Looking at Fig. 4 which is a rear view, it will be seen that during this movement or reciprocation (to the left as viewed in Fig.4) the gear II rides idly on the rack I0 carrying the pawl I2 to slip over the ratchet 1. Thus the turntable III is not turned about its vertical axis, but is simply moved linearly with the carriage. 3 to the left (Fig. 4).

Hence the article just molded is now at the position D (Fig. 3). The next matrix mold previously at the position E in Fig. 2 is now directly under the funnel I8I (see Figs. 1 and 4) to receive therefrom the next gob or mold charge. The mold part on turntable I8, previously at the position A in Fig, 2 where it received a mold charge, is now in position directly under the right hand patrix mold means 83 (see Fig. 1) where the mold charge is now being molded by the patrix mold die 83, the pneumatic means operating for that purpose at that instant,

The movement of this matrix mold part from position A in Fig. 2 to and under the die 83 in Fig. 3 was effected as follows referring now to Fig. 4) As the carriage 3 and the parts carried thereby was moved to the left, as viewed in Fig. 4,

and a component linear movement thereof with.

the carriage 3. In this position of the parts, the matrix mold, which has arrived at the position F, has dumped at position F upon the conveyor 53 the mold charge it carried (see Fig. 3).

The next movement is a reciprocation to the left from the position shown in Fig. 3 to that shown in Figs. 1 and 2, and to the right to the position shown in Fig. 4. Looking to the latter, it will be seen that the gear I l as it rides on the rack it turns with the pawl I2 locked with the ratchet wheel 1 to cause a turning of the turntable it by way of gears 13-45 (see Fig. counterclockwise and in the direction of the arrows, as shown in Figs.'2 and 3. Th'e other gear H (see Fig. 4) as it turns causes the pawl 52 to slip on the ratchet l and hence the table it does not turn but moves linearly only with the carriage 3. Hence the matrix mold with the fresh charge at position A (Fig. 3) has been moved in a path compounded from a rotation of the turntable it and a linear movement of the carriage and the turntable, to position B under the patrix mold part 83 and the matrix mold part on the table it now carrying the just molded charge at the position under the patrix mold part 83 has moved merelylinearly to position G (Figs. 1 and 2) The empty matrix mold part at position H in Fig. 3 has been moved to position A in Fig. 2 directly under the funnel itl to receive the next gob. This completes the cycle.

As the it-Ell carried thereby successively and eventually arrive over the lifting rods 5% (see particularly Figs. 1 and 7) there being a lifting device 5% for each table 18 and lt ing or dumping rack iQ-Et for each matrix mold. When the rack 49-50 is in alinement with the lifting means 5 5, the pneumatic means 62 (see Fig. 5) acts in given time relation to actuate the lever 59 and to lift the means 5fl-t95t, thus causing the corresponding matrix mold to swing and dump'the molded article, as shown in Figs. 2, 3,5 and 9 (in dotted lines in the latter).

The patrix mold means 83-8fl-B5 and 233 -84-85 are angularly adjustable about the axes of the plungers 85, 8t and the means 8?, 8? carried by the brackets 88 and 89 are adjustable both angularly about and axially of the axes of the posts'Qil, 98, whereby the position of the patrix' molds 83 and 8? may be properly related to the matrix molds when brought into molding positions under the patrix molds.
